UNITED STATES PATENT QFFICE.

AIMABLE A. GRANDELLE, OF NEW YORK, N. Y., ASSIGNOR TO THOMAS BROWN, OF SAME PLACE.

IMPROVED COMPOSITION FOR DYElNG THE COVERS 0F RAILROAD-SEATS, &c.

Specification forming part of Letters Patent No. 39,199, dated July '7, 1863.

To all whom it may concern:

Be it known that I, A. A. GRANDELLE, of the city, county, and State of New York, have invented a new and Improved Composition for Dyeing with Aniline Colors; and I do hereby declare that the following is a full, clear, and exact description of the same.

The principal object of this invention is to redye the cushions of railroad-car seats with aniline colors without ripping them open and taking them to pieces.

The invention consists in the application to the cushions after the same have been well cleaned from dust by beating and brushing of a composition madeby mixing together sulph uric ether, alcohol, and water in certain proportions, which will be hereinafter specified, for the purpose of removing the grease previous to applying the coloring or dyeing liquid, which consists of a solution of the desired color derived from aniline or analogous substances in sulphuric ether, alcohol, and water, mixed together in about the proportion and in the manner hereinafter specified. V

The articles to be dyed are first cleaned from dust by beating, and in order to remove greasy spots appearing on their surface the following composition is applied: sulphuric other, one pound; alcohol, four pounds; cold water, fourteen pounds. These ingredients are mixed together and applied with a hard brush. The

articles to be dyed are now left to dry, and then the following composition is applied: rosaniline, one ounce; sulphuric ether, one pound; alcohol, eight pounds; cold water, thirty-two pounds. These ingredients are mixed together and raised to a temperature of about 150 Fahrenheit and applied with a soft paint-brush.

Instead of rosaniline, any other color derived from aniline or analogous substances may be applied in the same manner by slightly altering the proportion of the solvents.

By this process such articles as cushions of railroad-car seats can be redyed without ripping them open, and the dyeing process can be completed in a few hours, so that it is not necessary to lay up a car, and the labor required to execute my process is of comparatively no account. It is obvious, however, that my process may also be applied with advantage to other articles of a similar nature to cushions of car-seats.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

The composition of matter herein described for dyeing cushions and other articles, prepared and employed in the manner herein set forth.

AIMABLE AUGUSTUS GRANDELLE.
